Abstract
一种带陷波器的可控变压器的动态潮流控制装置,由可控变压器、功率单元、测量与控制模块、旁路开关、陷波器、输入电压互感器、输出电压互感器和输出电流互感器构成,动态潮流的控制方法是利用迅速导通、关断的电力电子开关,控制可控变压器输出侧(副边)分接头的导通与关断,在脉宽调制信号中采取直流信号注入二倍频(或多倍频)信号,通过改变直流信号幅值和二倍频(或多倍频)信号的幅值与初始相位,从而改变可控变压器输出电压的相位、幅值,实现有功功率和无功功率的调节,通过陷波器,滤除可控变压器的动态潮流控制器输出电压的3次谐波(或与多倍频调制对应的奇次谐波),使得输出电压无畸变,具有成本低,动态潮流的控制可靠性高的特点。
The invention discloses a dynamic power flow control device for a controllable transformer with a notch filter, which is composed of a controllable transformer, a power unit, a measurement and control module, a bypass switch, a notch filter, an input voltage transformer, an output voltage transformer and an output current transformer. The control method of the dynamic power flow is to use a power electronic switch that is quickly turned on and off to control the on and off of the tap on the output side (secondary side) of the controllable transformer, inject a double frequency (or multiple frequency) signal into a pulse width modulation signal using a direct current signal, and change the phase and amplitude of the output voltage of the controllable transformer by changing the amplitude of the direct current signal and the amplitude and initial phase of the double frequency (or multiple frequency) signal, thereby realizing the regulation of active power and reactive power. The notch filter is used to filter out the third harmonic (or odd harmonic corresponding to multiple frequency modulation) of the output voltage of the dynamic power flow controller of the controllable transformer, so that the output voltage is distortion-free. The invention has the characteristics of low cost and high control reliability of the dynamic power flow.
